【摘要】 利用计算机软件,对某AP1000MW核电机组的超大型冷却塔进行了数值模拟,据综合计算,得出了冷却塔的喉部高度与塔高之比,确定了冷却塔喉部的上部曲率,并分析了喉部半径与零米处的半径之比。优化冷却塔的结构参数,减少了对出塔水温的影响。计算结果表明,当冷却塔的结构参数为特定值时,可提高冷却塔的性能。更多还原

【Abstract】 A super large cooling tower of AP1000 MW nuclear power unit was simulated according to the calculation by use of computer software,through comprehensive calculations,the ratio of cooling tower throat height and the tower height is gotten,the upper curvature of the cooling tower throat,and the ratio of throat radius meters and zero radius is analyzed.The structural parameters of the cooling tower were optimized to reduce the influence on the water temperature of the tower.The results show that the performance of the cooling tower can be improved when the structural parameters of the cooling tower are specific.更多还原
